Top Speed

To calculate top speed of an ebike with battery, you will need to consider the following factors:

• Battery voltage
• Motor wattage
• Gear ratio
• Tire size and pressure
• Rider weight and wind resistance
• Terrain conditions

However, it's important to keep in mind that real-world conditions can affect the actual speed, and safety should always be a top priority when riding. 

Average top speed: 

• X1 Pro & X1 Stealth: 60-70 km/hr 
• Photon: 30-35km km/hr  

Out of the chainring options we offer, the top speed and torque will be similar at the rear wheel, given that the 11/53 comes with the 32T chainring.

11/63T comes with 38T chainring, and 11/72T comes with 40T chainring. 

11/72T will be the best for cadence. 

11/63T will be the best balance if you like higher ground clearance.
